how many valence electrons does carbon have?

First Method:

The first easiest methods for finding the number of valence electrons for carbon atom or any different atoms, first look at the periodic table, if you properly look at the periodic table then you can see that, carbon in group 14. this is also called as 4a group. this mean, 4 valence electrons. so, according to above information, surely, we can say that carbon atom have 4 valence electrons. this is the easiest and better method to find out the valence electron for any different atoms.

Lets know , with electron digram for carbon atom.

Atomic number of carbon atom is 6. this is the number of porton. If the neutral then we have 6 electron.

the inner shell contain 2 electron out of 6. then outermost shell have remaining 4. it mean, valence electron in outermost shell is 4. as shown in electron digram.

Secod Methods:

The other method is use to finding valence electron for any different atoms is, use the electron configuration. this is also easier techniques for calculating valence electron for an atoms.

Here, i m going to discuss about how to identify valence electron for carbon atom. First need to draw the electron configuration of carbon atom. if you look at the periodic table, you can see that the atomic number of carbon is 6. this is the number of porton.if neutral then we have 6 electron. it is also called number of electron.

Now, i m going to draw electron configuration for carbon atom.

Now, if you loot at the electron configuration of carbon atom. we can write electron configuration for carbon atom, first 2 electrons will go in the first orbital. since, 1s orbitals can only hold 2 electrons. and next 2 electrons for carbon atom will goes in the 2nd orbitals.

You know that, 2nd orbital has capable to hold only 2 electrons. and remaining 2 electrons for carbon atom will go in the 2p orbital. and 2p orbital can hold 6 electrons. but in case of carbon atom only need 2 electrons.

Therefore, we can write the electron configuration for carbon will be,

Finding the number of valence electron for the carbon, only you look highest energy in electron configuration.

Write the order of higest energy, for electron configuration of carbon atom. you can add then you can see that there are 4 valence electron for the carbon atom in second energy level.

therefore,

we can say that the valence electron of carbon is 4.
